Application filed March a, 1914. Serial No. 822,471.

To all whom it ma concern:

Be it known t at we, HENRY J. CARBIS and SAMUEL H. CARBIS, citizens of the United States, residing at Freeport, in the county of Armstrong and State of Pennsylvania, have invented a new and useful Valve, of which the following is a specification.

The present invention appertains to valves, and aims to provide a novel and improved valve construction.

It is the object of the present invention, to provide a valve embodying a plug or spigot, andprovided with unique means whereby when the plug or spigot is rotated to ope n position, the same willbe moved longitudinally slightly to create a slight clearance between the plug or spigot and its bore, for clearing the adjoining portions of the plug and its bore, of any corrosion, sediment and other extraneous matter, the plug or spigot being returned to normal position when the same is opened and closed, to facilitate the regrinding action between the plug and its bore or seat.

It is also within the scope of the present invention to provide a valve construction of the nature indicated, which will be improved generally in its details, whereby the valve will be comparatively simple, durable and inexpensive in construction, as well as being simple, convenient, practical, serviceable and eificient in its use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and m the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein- Figure 1 is a longitudinal section of the valve, in open condition, parts being broken away. Fig. 2 is a similar section taken at right angles to the plane of section of Fig. 1. Fig. 3 is a cross section taken on the line 3-3 of Fig. 1. Fig. 4: is a cross section taken on the line 4-4 of Fig. 2.

The present invention embodies the shell or body 1 having the tapered bore or valve;

seat 2 therein, and the inlet and outlet ports 3 extend1ng to the bore 2, the bore 2 bein disposed longitudinally of the body or sliel 1, and the ports 3 protruding laterally for connection with the sections of the. pipabetween which the said valve is adapted to b,e 1nterposed for controllin the flow of the fluid through the pipe. hat end of the body or shell 1 adjoinin the smallest end of the bore 2, is provide with a threaded counter bore or socket 4, while the other end of the body or shell is provided with a counter bore 01' socket .5, which is also threaded.

isprovided with a diametrical passage 7 adapted to be swung into and out ofreg' stration with the ports 3 of the shell or casing 1. The lower or large end of the plug 6 18 provided with a depending boss or lug 8 prpjectiig into the counter illiore1 orsocket 5.

n or er to sprin presst e u Gsnu l or ti htly within tile bore 2, a bug 9 is p l o vide with a relatively thick outturned flange 10 at its rim or margin, has the flange 10 threaded into the counter bore or socket. 5 adjoining, but spaced slightly from, the largest end of the plug 6. A binding or retaining nut 11 is threaded into the counter bore 5 to contact with the flange 10, for locking the cup 9 in place, it being noted that the mouth or open end of the cup' is disposed innermost or uppermost so as to receive the boss or lug 8 of the 1g, The binding or jam nut 11 is preferalbly locked or retained within the counter bore 5, by means of a split locking ring 12 shaped into an inner annular groove 13 provided in the walls of the counter bore 5. An adjusting screw 14; is threaded through the bottom of the cup 9, and is provided in its upper or inner end with a concaved seat or recess15, and a disk or spring seat 16 disposed loosely within the cup 9, has a rounded knob or lug 17 engaging the seat 15 of the adjusting screw, to enable the disk or spring seat 16 to rotate or vibrate with respect to the adjusting screw. Coiled wire com ression springs 18 are seated between the 'sk 16 and the lower or largest end of the plug 6, around the boss 8. Attention is directed to the fact, at this point, that the disk or spring seat 16 being rotatable, will enable the springs 18 and seat 16 to rotate or swing 85 relative to the plug,

50 provided at diametricall with the plug or spigot 6, to avoid friction between the springs and the plu and to enable the plug to be forcedsnug y withm the bore 2 in the most effective manner. The disk or spring seat 16 will readily accommodate itself to the springs 18 and their tension may be regulated by ad ust1ng the screw 14, as will be evident.

In order to manipulate or rotate the plug or spigot 6, a collar or ring 19 is threaded into the counter bore or'socket 4 at the upper end of the shell or casing 1, a binding nut 20 being threaded upon the upper or outer end of the ring 19 and bearing against the corresponding end of the body or shell 1 to retain the ring 19 in place. The ring 19 is provided with a stufiing box 21, into which is threaded a 'gland 22, and a smooth valve stem-23 is journaled through the ring or stuffing box member 19 and the gland 22,

the gland serving to compress the paclnng within the stuffing box 21 so as to embrace the stem 23 to prevent leakage.

The lower end of the stem 23 projects be- 25 low the stufling box member or ring 19, and

is provided with a vvdiametrical tongue 24,

. the ends of which project beyond the sides of thestem 23, to form fingers or pro'ections, snugly engaging the upper or smal est end of the plug 6, and working between a 7 pair of sectoral stops 25 formed upon the upper or smallest end of the plug. this manner, the stem 23 WlllCh 1s mdepe'ndent of the plug, has limited oscillatory movements it being noted that when the stem 23 is rotated in one direction, the fingers 24 will engage certain s1des of the stops 25 to rotate or swing the plug with the stem, and when the stem is rotated m 40 the opposite direction, the fingers 24 will engage the other sides of the stops 25 to correspondingly move the plug.

In order to depress or move the plug longitudinally against the tension of the 4 springs or yieldable lifting means 18, a ring or annulus 26 is mounted within the lower or inner end of the counter bore 4, and loosely embraces the lower or inner end of the stem 23, the ring or annulus 26 being opposite points, with depending cams 27 ying in the paths of the fingers 24. The ring 26 is disposed above the fingers 24, and seats agamst the bottom of the stufling box member 19, the

ring 27 being restrained against oscillator movements, by means of a lug or rib 2 formed upon one side of the mug 26 and engaging one of a series of notches 29 formed upon the interior of the counter bore 4.

Thus, by engaging the projection or lug 28 with the respective notches 29, the ring 26 may be adjusted angularly with respect to the plug and stem, for positioning the cams 27 to the points desired or most approprlate. A pointer 30 is preferably carried by the actuating stem 23, to operate with the cor responding end of the shell or casing 1, the shell or casing being preferably provided with indications thereon, cooperable with the pointer, whereby the positions of the plug or spigot may be readily determined.

In operation, the ring 26is so arranged, that when the plug is in closed position, the fingers 24 will be released from the cams 27, the springs 18 serving to force the plug snugly or tightly into the bore 2. Thus, when the passage 7 of the plug is out of register with the ports 3, the plug will effectively close the ports 3. To open the valve, the stem 23 is rotated in one or the other direction, causing the fingers 24 to engage the stops or projections 25 of the plug, to thereby correspondingly rotate the plug to bring the passage 7 thereof into registrat1on with the ports 3. After the plug 6 has been moved into open position, the fingers 24 are arranged to engage the cams 27, which will cause the stem 23 to be forced downwardly or longitudinally, to thereby move the plug or spigot 6 downward or longitudinally slightly to provide a slight clearance between the plug and the bore 2, whereby the corrosion, sediment or other foreign matter between the bore 2 and the plug 6 may be cleared out or ejected. As soon as the stem 23 is rotated to close the valve, the fingers 24 will be released from the cams 27 to again return the plug 6 to normal position, under the influence of the spring 18, it being noted that as the plug is opened and closed, the same will be given a slight longitudinal movement, which will facilitate the regrinding action between the plug and the bore 2, to cause the plug to engage snugly within the bore to prevent leakage when the valve is closed. V It will therefore be manifest, that the present valve is of such construction, as to enhance or facilitate the regrindmg action between the plug and its bore or seat, peculiar means being provided for actuatmg and spring pressing the plug or spigot to the ends desired. The other advantages and capabilities of the present valve will be obvious to those versed in the art and further comment is deemed unnecessary.

Having thus described the invention, what is claimed as new is:

1. A valve embodying a body havin a bore, a spring pressed plug fitting the bore, a rotar stem carried by one end of the body adjoining one end of the plug, the said end of the plug having stops, one end of the stem bearing against the said end of the plug and having a finger movable between the said stops, and a cam mounted within the body in the path of the said finger to move the stem longitudinally against the said end of the plug when the stem is at a predetermined position.
